Heat Risk Analysis
Shelley in Western Australia faces elevated extreme heat risk. The Bureau of Meteorology (BOM) reports that Australia's average temperature has increased by approximately 1.5 °C since 1910, with the frequency of extreme heat days rising across most regions.
The urban heat island (UHI) effect can make built-up areas of Shelley warmer than surrounding rural areas, particularly on summer nights. Dark roof materials, limited tree canopy cover, and heat-absorbing surfaces contribute to localised heat stress that varies by property.
Perth experiences several heatwave events each summer, with temperatures exceeding 35°C. Shelley is subject to the same heatwave conditions as the broader Perth metropolitan area.
Get an address-level heat risk assessment from ClimateNest for Shelley including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Shelley (postcode 6148) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (17.4% of land in high-risk zones), surface flood (11.1% of land in high-risk zones), extreme wind (5.9% of land in high-risk zones). Exposure is not uniform across Shelley — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions
How hot does Shelley get in summer?
Shelley in Western Australia experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Shelley. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Shelley?
Australia-wide, extreme heat events have become more frequent since the mid-20th century, and this trend is consistent with CSIRO climate projections for Western Australia. Continued warming is likely through 2050 under all emissions scenarios.
How does heat affect energy costs for Shelley properties?
Higher temperatures increase cooling demand, which raises electricity costs. ClimateNest provides energy cost projections based on your property's specific exposure to extreme heat days in Shelley and the performance of your building envelope.
What heat mitigation measures work best in Shelley?
Effective heat mitigation includes light-coloured roofing (cool roofs), ceiling and wall insulation, double-glazed windows, external shading, cross-ventilation design, and increasing tree canopy around the property. These measures reduce indoor temperatures and cooling costs.
What share of Shelley is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 17.4% of Shelley in high-risk zones for bushfire, with a further 66.8% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
